Folks:
If this turns out to be a multi-post, or multiple posts, I apologize. OE
crashed the first time through.
I am converting some dxf files to a povray triangle format. In doing so, I
have found some triangles which won't parse:
This one works.
triangle{
<-0.9 0.0 0.1>,
<0.0 0.1 -0.8>,
<0.1 -0.8 0.3>
}
This one doesn't.
triangle{
<-0.9 0.0 0.1>,
<0.0 0.1 -0.8>,
<0.1 -0.8 -0.3>
}
The only difference is the sign of z in the last vertex. The actual value
doesn't seem to matter. It parses if the sign is positive, and chokes if
the sign is negative It tells me "expected a numeric value, found a >
instead".
Shouldn't any three discrete points be a valid triangle? Any clues to what
is wrong (and how to fix it) would be appreciated.
TIA,
Alan Walkington

try seperating the values with commas
in the first example pov is probably trying to parse it as <0.0, 0.1-0.8,
missing value>
